Positions and why they change everything

Where you sit decides how much information you have. It's the most important factor in poker.

In poker you don't just play your cards: you play your cards from a position. Position defines how many opponents act after you, and therefore how much information you have when you decide. It is, without exaggeration, the most profitable variable in the game.

The order at a 6-max table

From earliest (acts first) to latest:

PositionOpens ~Character
UTG~17%Early — tight
HJ~21%Middle
CO~27%Steal — wide
BTN~45%The best — very wide
SB~40%Blind — bad postflop position

Why does it matter so much?

Acting last is a brutal advantage: you see what everyone does before you decide. That extra information lets you extract more value when you win and lose less when you're behind. That's why from the button you open mediocre hands profitably, while from UTG you need solid hands.

Ejemplo98 is an easy fold from UTG (too many people behind), but a standard, profitable open from the button: same hand, opposite decision — the difference is position.
⚠️ Error común: Playing the same hands from every position. The big leak among beginners is calling with hands like A9 or KT from early positions, where they're dominated.
✓ Consejo: Before you look at your cards, look at your position. It will save you more money than any opponent-reading trick.
💡 Clave: The better your position, the more hands you play and the more money you win with them. Position is the backbone of every decision.
